· The excessive bank angle alert is a function of the roll angle with respect to altitude above
ground level. The alert envelope varies linearly from a 10° bank at 30 feet AGL and to 40° of
bank at 150 feet AGL, to 55° of bank at 2450 feet AGL. This will generate an aural “BANK
ANGLE, BANK ANGLE”. The alert is annunciated once and will repeat if the bank angle
increases by 20%. The alert will be annunciated continuously if the bank angle is increased
to 55°. The alert will be annunciated until the bank angle is decreased below said value.

Mode 7 − Windshear Warning
Mode 7 provides alerts and warnings in the event that significant windshear is detected by the
EGPWC. Mode 7 is active during takeoff
and landing phase of flight only, between 10 and
1500 feet AGL. There are two types of windshear warnings: increasing performance
(updraft/headwind) and decreasing performance (downdraft/tailwind).
· When the EGPWC senses an increasing headwind (or decreasing tailwind) and/or a severe
updraft, an increasing performance annunciation WINDSHEAR will be posted on the PFD. It
will flash for 5 seconds then remain steady.
· When the EGPWC senses an increasing tailwind (or decreasing headwind) and/or a severe
downdraft a decreasing performance annunciation WINDSHEAR will be posted on the PFD.
It will flash for 5 seconds, then remains steady and an aural siren and “WINDSHEAR,
WINDSHEAR, WINDSHEAR” warning are activated.

Windshear Flight Director Mode Annunciations
The WSHR mode can only be activated when a windshear warning is present. The mode can be
activated by depressing either TOGA button on the thrust levers or by pushing either thrust lever
beyond 37 degrees. If however the airplane is already in TOGA mode, or has either thrust lever
beyond 37 degrees at the point at which the windshear warning is posted, the mode sets
automatically.
The WSHR mode cannot be cancelled when a windshear warning persists. Any selection of the
FD or AP engage buttons are ignored but yaw damper function is unaffected. Once the windshear
warning has cleared, WSHR mode can be cancelled by any selection of FD or engagement of AP.
A WSHR mode annunciation is displayed on the vertical mode and a ROL mode annunciation is
displayed on the lateral mode. GF1710_080

Windshear Escape Guidance
The windshear mode will provide windshear escape guidance consisting of lateral and vertical
modes as follows:
· Vertical guidance will provide optimal escape guidance.
· Lateral guidance will be provided to maintain wings level.
A pitch limit indicator and windshear annunciation are displayed on both PFDs, during an
increasing or decreasing performance windshear. The pitch limit indicator will differ depending on
selection of Single Cue or Cross Pointer.
